Before riding Karacho I was intrigued by the prospect of finding out whether we'd really missed out with The Smiler not getting lap restraints. My conclusion after riding it was that we have, just not by as much as you might think.
I was hoping for a nicely shaped lap restraint that would stay in one place and remain comfortable during the ride, but I was actually expecting an ergonomically imperfect lump that would be pressing on my thighs by the brake run (this is Gerstlauer after all). Unfortunately the restraint design is nowhere near the standard of Mack's mega coaster OTSLR design and turned out to fulfil my expectations.
When you take your seat in the station it's perfectly acceptable. Not as comfortable as it could be, but not bad either. It's slimmer than you'd think and combined with the basic seat it makes you feel very exposed. It's best to have it tight from the off, as the roll before the launch is...interesting even if you're held in tightly. Once you get outside you realise that having it slightly loose would be pointless anyway, as it gets tighter during the ride and will be trying to crush your thighs just as much as an OTSR would by the brake run. There's a limit to how tight they can get with your legs in the seat of course, but I still wonder whether Smiler would possibly be even worse for this as Karacho is nowhere near as intense (we were told that the launch runs at 83-85% power to reduce the height/age limits; the result is a good ride that nonetheless feels frustratingly slow in places and is obviously running below its potential, rather than the great, Smiler-intense coaster that might be waiting to come out on full power
).
Lower body comfort then isn't really any better, but I'd still like Smiler to have these restraints for the upper body freedom. The main advantage is not having to worry about keeping your head forward out of the OTSR's way. The feeling of exposure is where I think Towers have really missed a trick though, as this combined with Smiler's tangle of track, supports and head choppers would be fantastic and would terrify many UK guests! >
Towers, if you're reading this, I urge you to get Gerstlauer back in for some lap restraints (but perhaps suggest a system to lock them in place upon leaving the station).
